KEY DIGITAL HD LEEZA, MODEL KD-HD1080P
HD Leeza Operating Instruction Manual SPECIAL SECTIONS
Q: What happens if the HD Leeza Input source is DVI/HDCP ?
A: Remember that DVI/HDCP requires that the analog output ports of HD Leeza must (by law) be
disabled for HD content, and hence only the DVI output of HD Leeza is permitted to be active for
DVI/HDCP sources.
Q:
The scaled, analog output of my HD Leeza contains dark horizontal bands (perhaps intermittent but
frequent, with the position of the bands changing constantly).
A: There could be two reasons:
1. Your display clamping is not where it supposed to be. You can change the position of the clamping pulse
in the menu of your monitor if you have such setting OR you can adjust the horizontal position of the HD
Leeza output in the System Setting menu. You probably need to move the image
right .
2. HD Leeza is clamping in the wrong position. Adjust the HD Leeza input H position -- it is individual for
each input channel.
Q: I have a Sony HDTV Set-top Box (STB) with VGA (RGBHV) and Component YPbPr outputs.
Which mode should I use to connect to HD Leeza?
A: We recommend you use Component YPbPr, 1080i for STB's because YPbPr is the native HD
broadcasting format. The RGBHV is a derived (“second generation”) signal inside the STB. To
make the YPbPr connections, you can use RCA-to-RCA cables and add three RCA-to-BNC jack
converters on the HD Leeza side (e.g., readily available from Radio Shack). To use this connection
make sure the switch on the back of the Sony STB for output TYPE is set for YPbPr, 1080i. On HD
Leeza through the menu you need to switch to HD Inputs, Component HD.
Q:
When using VCR tapes at the composite video input to HD Leeza, there seems to be a “timebase”
issue – very “juddery” images. Does HD Leeza require a VCR with a Time Base Corrector (TBC) at
the input? Does HD Leeza have any internal time base correction?
A: While HD Leeza does have a built-in TBC , it is not designed to compensate for large errors that may
come from a VCR. It is best to use a VCR that is readily available today with a built-in TBC; or use
an external TBC at the output of the VCR before you feed the signal into HD Leeza.
Q:
The HD Leeza test patterns all seem to have a fixed resolution. For example, on my 1024x768
display, I can only see a little more than 4 color bars, the cross pattern only shows a vertical line far
to the right on the screen, etc.
A: The test patterns are “full” only in 1920x1080 . In any other resolution, the test patterns are a
subset of 1920x1080.
Q:
I am having trouble with individual memory inputs .
A: Use the following guidelines:
1. First switch to the desired channel using the OSD. Then, set the parameters for Brightness, Contrast, etc.
2. RESELECT that same input using the OSD. After reselection, the OSD will pop offering you an
additional window for "
Restore PA " or " Memorize PA ". The current HD Leeza settings become individual
memory for that input when you select " Memorize PA ".
3. HD Leeza will use these stored settings the next time you use the OSD switching and choose " Restore
PA ".
